Rachel Bilson: Sweet Aroma Cafe!

Former O.C. actress Rachel Bilson and a mystery male (not fiance Hayden Christensen) grab a bite to eat at Aroma Cafe on Tuesday afternoon (June 9) in Studio City, Calif.

Duff sisters Hilary and Haylie frequent the same yummy eatery, as well as High School Musical sweethearts Zac Efron and Vanessa Hudgens.

Love Rachel‘s cardigan and patent booties! She also toted around Jimmy Choo‘s “Sky” Patent Bag.
